1&rpar;&comma;LB-JF high vacuum model dust collector adopted international advanced polyester fine filtering technique&comma; can be effective absorption and filtration the smoke micro &lpar;0&period;2 um&rpar; of the welding&comma; cutting and grinding process&comma; filtration efficiency can reach 99&period;9&percnt;&period; At the same time and high gas flow is guaranteed&period;

2&rpar;&comma; the purifier has low noise&comma; stable performance&comma; convenient operation and use and many other advantages&period;

3&rpar;&comma; this product is double filter&comma; the first level for Mars filter and larger particles&comma; secondary to tiny dust filter&period;

&ast;&ast;&ast;Operating Principle&colon;

Under the device's high negative pressure&comma; the fume and dust through suction pipe into the purifier&comma; with the Martian dust before enter the purifying cavity were blocked and separated by fire sand&period; The remaining dust flow is blocked and uniform distribution by flow plate inside the purifying cavity&comma; in order to better purify by cartridge filter&period;Larger particles of dust under the action of gravity sinking into the collection of ash hopper&comma; while small particles of dust under the action of suction generated by the eddy current is suspended in internal to purify by cartridge filter&period;Small particles of dust on the surface of the filter cartridge&comma; after the effect of gathered adsorption and combined&comma; sinking into the ash hopper&period; After purification&comma; the air flow out&comma; offer a healthy working environment for workers&period;
